Hi Hans!
Yeah! Direct netboot is a very nice idea too... I can't to it with one kind
of server I'll have but with the clustered ones that I'll be nice! To
improve reliability I could make a copy of a healthy image to the node's
hard drive every time it boots, so it's not dependent on a NFS server all
the time (just to boot).
Best
Daniel
